Wonderful skeletal! Can I ask you a thing? Why you reconstructed the "beak" of this animal in this way? 'Cause in the few skeletals I've seen of this ornithopod, there were always deeper and more robust snouts that never looked like that of a lambeosaurine. But probably it's just me

Thanks! It's because that the original praemaxilla bones was deformed and flattened. The all other skeletals of Olorotitan based only on photos of the mounted skeleton (Belgian cast). The fact is on this copy of the skeleton you can see only original (cast) deformed praemaxilla that are placed its dorsal surface more laterally. In the Russian mounting of the skeleton this part of skull was restored.

No, it's all the holotype. I just made new interpretation of the crest after I saw and studied it. I will show the parts which are present and not. So you can see which part of the crest (nasal) is present.
